VISE.

SPECIFICATION forming partof Letters Patent No. 237,331, dated February1, 1881. Application filed December 9, 1880. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM E. SNEDIKER, a citizen of the United States,residing in the city of Trenton, county of Mercer, and State of NewJersey, have invented certain new and useful Improvements in Vises,fully described and represented in the following specification and theaccompanying drawings, forming a part of the same.

This improvement relates to means for attaching a vise to the bench thatsupports it, so that the same may swivel, and thus be rendered capableof having its jaws disposed at such angles with respect to the benchthat all shapes of work held by the vise may be securely held in suchrelation to the workman as to be conveniently operated upon.

The invention consists in mounting one leg of the vise in a journal ofpeculiar construction, whereby the vise is 'not only rendered capable ofbeing moved to any desired angle, but may be secured firmly in anyadjusted position.

In order to a perfect understanding of my improvement, I will nowproceed to describe the embodiment of it illustrated in the annexeddrawings.

In said drawings, Figure 1 represents a side elevation of a viseprovided with my improvement. Fig. 2 represents a front elevation of thesame, partly in section. Fig. 3 represents an enlarged sectional planview (line as) of the swivel bench-clamp, and Fig. 4 represents avertical sectionalelevation (line 3 of the same.

The form of vise to which my attachment is especially adapted is theleg, or that variety in which the leg to and is stepped in the floor,and to which leg 2 the leg 4 of the movable jaw 5 is pivoted, the latterbeing moved or opened and closed by means of a screw-bolt, as 6, and alever, as 7. Ordinarily this class of Vises is attached to the bench 8by means of a socket-plate or other fastening, that permanently fixessaid leg in place, so that it may have no movement, and thus sustain thejaw 3 rigidly in place. Such an arrangement of the parts limits thecapacity of the vise so far as to render it inconvenient and laboriousto operate upon certain classes of work that require it to be held 2 ofthe fixed jaw 3 extends in an angular position relative to the bench towhich the vise is attached. To avoid these defects many complexstructures have been made, all of which have required the generalreorganization of the vise, so as to capacitate it not only to swivel,but to be secured in its various adjustments. These new structures areeither defective in their capacity for heavy work, or else require aconstruction of swivel involving comparatively great expense inproviding the requisite extent of bearingsurtace necessary to impartsufficient strength to the machine.

In carrying out my improvement I preserve the general form of the viseand provide it with a swivel-joint, as follows: I fit its leg 2, theform of which is generally rectangular, with bearing-blocks 9 10, (seeFigs. 3 and 4,) which blocks have flatinner faces, fitting upon thesides-0t said leg, and rounded outer faces, that, together with curvedfront and rear faces of the leg 2, constitute a circular journal, as inFig. 3, that is adapted to be seated in a circular bearing formed by asocket-plate, 11, and a socket-strap, 12. The socket-plate 11 is firmlysecured to the edge of the bench 8 by nuts 14 or otherwise, so as toafford a rigid support, and the socket-strap 12 held upon saidsocket-plate 11 by means of screw-bolts 15, that are constructed so thatthey may be readily turned to cause the strap 12 to press inward more orless forcibly, and thus operate with the plate 11 to clamp the leg 2 andits mounting, and thereby hold it and the vise it supports in anyposition of radial adjustment, and on the other hand cause its clampingeffect to be modified so as to permit the leg 2 and the vise to be swungradially into any desired position of adjustment and there be secured.

The structure described is of course designed as the mountings adaptedfora vise constructed with a leg, as 2, which has or is provided withfiat sides and front and rear edges, that are or may be rounded,as isillustrated, and it is to be understood that the bearing-blocks 9 l0,constituting in part such mountings, will be provided with overhangingedges, as 1, or some other means, as a horizontal rib projecting fromthem and entering the socketptate 1] and strap 12, or vice versa, toprevent their being displaced from their seats.

It will be obvious from the foregoing that the form of the leg 2 may bepolygonal and the blocks 9 10 be adapted to fit upon it and constitutethe circular bearing.

In structures where it is desired to dispense with the elongated form ofthe leg 2, or where such leg is of about the length of its companion leg4, the socket-plate 1.1 and strap 12, as well as the bearing-blocks 910, will be elongated so as to so far embrace the leg 2 as to afford thesupport requisite to sustain the rigid vertical position of the vise, nomatter what its radial adjustment may be.

By the use of the socket-plate l1 and the adjustable socket-strap 12 thevise is rendered capable of adjustment to any radial position desired,where it may be firmly secured, and the structure of the swingingdevices is such as not to impair the strength of any of the parts of thevise.

What is claimed is-- The combination, with the polygonal leg, a 2, of avise, and bearing-blocks, as 9 10, where by said leg is provided with acircular bearing, of a socket-plate, as 11, and a socket-strap, as 12,substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

W. E. SNEDIKER.
